HOBOnode sensors monitor temperature and soil moisture conditions and wirelessly transmit the data back to your computer.

Features:

Fast, easy deployment - sensor's compact size, integrated solar-rechargable battery makes deployment a snap.
.0 to 100% soil moisture range
Software provides real-time graphs and alarms to cell phones or local PC; data can be exported for use in other programs.
1400 ft. line-of-sight transmission range, up to six miles with HOBOnode Repeaters
Research-grade reliability and accuracy
Complete system requires: Receiver, Sensor, HOBOnode Viewer software. A Repeater is required for greater distances.(all sold separately)
Includes bracket for convenient mounting on pole or stake
